300,000 Volt Hand Driven Van De Graaff Static Electricity Generator

This hand-cranked Van de Graaff with 300 kV potential, including instructions and accessories, is essentially a turn-key operation. Set it on your lab table, invite a volunteer to start cranking, and then demonstrate the static electricity produced. The globe is highly polished and seamless stainless steel 10" in diameter, and the instruction booklet describes a host of experiments as well as explaining in detail how it works.

Several accessories are also included:

40 cm (16") discharge wand with plastic handle

Electric whirl

Electric plume

Point discharge needle

Due to the size and weight, extra shipping may need to be calculated after checkout.

Our standard model 400kV Van de Graaff generator will jump sparks, raise hair, light bulbs, and any number of experiments and demonstrations. Great way to study electrostatic principles. We suggest using our VDGWAND-TALL Discharge Wand for best results and maximum spark distance.

Van De Graaff Grounding Wands

Portable Wand.This hand-held wand consists of a 10.5cm diameter highly polished stainless steel sphere mounted on a 40 cm insulated plastic rod. With banana plug and alligator clip to ground most Van de Graaffs. The discharge wand proves a convenient way to discharge the collectors of Van de Graaff generators. This is particularly useful when demonstrating hair-raising. By discharging the collector, the student does not feel a shock when touching the generator. The wand can also be used to draw arcs from the Van de Graaff which can be seen from a distance for an effective demonstration in front of large groups.

Short Wand.Bring the power of a lightning bolt into your classroom or museum. Here's an easy yet dramatic way to discharge Van de Graaff Generators in full view of the largest crowd. With the top aluminum oblate terminal about 7 inches in diameter and 5 inches high, mounted on a 12" stand to place alongside a Van de Graaff generator at different distances for different discharge sparks, it can also be picked up and used as a handheld wand.

Volta's Hailstorm

Demonstrates the mechanical forces produced by electric charge

When near an active Van de Graaff Generator, the tiny conductive balls inside begin to bounce up and down. It looks as if the pieces are "hailing" as they skitter and rebound. The explanation lies in the fact that the floor and ceiling of the cage become electrically charged. The Van de Graaff builds up a charge by induction as electrons are transferred from the ceiling to the floor. Since the balls lying on the floor are now negatively charged, they are attracted by the positively charged ceiling. But when the balls hit the ceiling, their negative charge is neutralized and they become positively charged instead. Down they fall to the negatively charged floor where they become positively charged upon impact. Back and forth, upwards and down - a veritable "hailstorm in a teapot." This flurry of activity will last as long as the Van de Graaff generator is running.

Volta's Hailstorm includes:

Transparent cage mounted on sturdy metal base (9" in diameter)

Ball terminal to attract electric charge

12" high, can be seen from a distance

Tiny polystyrene balls

Instructions with theory

Leyden jar

Is actually a high voltage capacitor used in the embryonic stage of the discovery of electricity

Charge it, dissect it - holds a charge for hours. Prove that a charge is stored in the dielectric insulator, not in the metal surfaces. Includes: 2 aluminum cans, polystyrene dielectric, electrode with ball terminal, instructions with lab activities. Wt: 9 oz.

Electroscope

A way to measure very small electric charge. Another device ushering in the age of electricity.

Detect an invisible electric wind from a Van de Graaff with our static spinner. since pointed objects carry a much greater concentration of electric charges than the Van de Graaff's sphere, the spinner will rotate rapidly when in its vicinity. Consists of a metal base, 9" diameter spinner on cone bearings for easy movement, and instructions with theory.

Electric Plume

Demonstrates the forces repulsion by like charges quite dramatically

Need a way to demonstrate electrostatic repulsion without a model? This "head of hair" makes a good substitute. Attach the suction cup on the base of the plume to the globe of the Van de Graaff generator. Turn on the machine and watch each strand of "hair" stand away from each other. The reason, of course, is that each strand has the same electric charge and repels its neighbor. With instructions.

A fun accessory for your Van de Graaff generator!

Lightning Leaper

Even electricity will follow the path of least resistance. This printed circuit board proves it. It consists of an insulating plate with two binding clips on either end for connecting to a Van de Graaff. On the plate's surface, an incomplete metal path is drawn. Watch the electricity leap over each gap! 10 x 20 cm in size, with two binding clips and instructions.

Wimshurst Machine, Deluxe

Unlike many others we have tested, this one works really great!

This device generates static electric charge at higher current (and lower voltage) than the Van de Graaff. It consists of two high resistance plastic discs with equally spaced metal sections. The discs rotate in opposite directions with a hand crank, producing substantial opposite charges which are deposited in the capacitors and on the metal electrodes. You can collect induced charge with the brushes and adjust the electrodes and Leyden Jar capacitors for higher potential. Fully assembled, mounted on plastic base, works right out of the box.
